Embodiment Construction

[0013] Application of normally open solenoid valve in air conditioning system with water heater:

[0014] When the system is in cooling operation, the two solenoid valves are not powered on, and the superheated gas of the high-temperature and high-pressure refrigerant discharged from the compressor enters the finned heat exchanger of the outdoor unit through the four-way reversing valve to release heat, condenses the refrigerant into liquid, and passes through the filter, After throttling and reducing pressure through the one-way valve and the restrictor, it enters the finned heat exchanger of the indoor unit for evaporation and cooling through the solenoid valve and the filter, and then enters the suction port of the compressor through the four-way reversing valve to realize the cooling function.

[0015] When the system is heating, the two solenoid valves are not energized, and the superheated gas of the high-temperature and high-pressure refrigerant discharged from the compr...

Abstract

The invention relates to a normally open type electromagnetic valve, which is applied to flow direction controlling products with multi path air flows or liquid flows. The components of the normally open type electromagnetic valve comprise a valve base, a valve core, a valve gate, a magnet coil, a spring, an electromagnetic core, and an inlet and outlet connecting pipe, etc. When the power of the normally open type electromagnetic valve is cut, the valve core is moved leftwards under the action of the spring force, thus a slit is formed because the conical surface of the valve core leaves the conical surface of the valve base, air flow or liquid flow passes the slit, and a pathway is formed; when the power is switched on, the valve core is moved rightwards under the action of the electromagnet force, the conical surface of the valve core adheres to the conical surface of the valve base, and thus air flow or liquid flow can not pass. When the normally open type electromagnetic valve is used in an air conditioner with a water heater and the system is in cooling and heating conditions, two electromagnetic valves are powered off, and when the system separately supplies hot water and when the system cools and supplies hot water, only one electromagnetic valve is powered on, thus not only the electric energy is saved, but also the service life of the electromagnetic valve is prolonged.

Description

technical field [0001] The invention is suitable for refrigerant pipeline design and flow direction control system in the air-conditioning industry. technical background [0002] At present, the solenoid valves used are all normally closed. This solenoid valve has a simple structure and low cost, but its solenoid coil must be continuously energized. In order to prevent the solenoid valve from being energized for a long time and increase its service life, a normally open solenoid valve can solve the problem. Contents of the invention [0003] The structure diagram of the normally open solenoid valve is shown in the "Instructions Attached". [0004] 1. Structural design [0005] The normally open solenoid valve is mainly composed of a valve seat, a valve core, a valve, an electromagnetic coil, a spring, an electromagnetic core, and an inlet and outlet pipe. When power is off, the spool moves to the left under the action of the spring force, and the conical surface of the...
